Integrated magnetization technology employs post-assembly magnetization process where unmagnetized magnets are installed on motors and subsequently magnetized using pulsed coils. Unlike traditional pre-magnetized methods, it offers three key advantages: simplified mechanical structures, reduced energy losses, and precise multi-pole synchronization. Current integrated magnetization faces challenges like excessive energy demands, and reliability issues due to magnetic field gradients and thermal stress. This requires a new integrated magnetization scheme to address these. The tangentially magnetized permanent magnet motor used in this study is widely employed in electric vehicle traction systems and industrial servo systems. Its tangential magnetic circuit design facilitates concentrated flux distribution, thereby achieving enhanced air-gap flux density. Excessive magnet embedding depth in tangential magnet motors increases the gap between the permanent magnet and the coil, leading to incomplete integrated magnetization. To resolve the challenges, this study proposes an integrated magnetization design for tangential permanent magnet motors. By integrating an optimized dual-coil configuration with copper yoke constraints, the design achieves significant performance improvements under identical power conditions, including achieving full saturation magnetization. The optimized positioning of the copper yoke constraints effectively suppresses demagnetization effects in adjacent poles. Meanwhile, it stabilizes coil operating temperatures within permissible limits. This technological advancement provides an energy-efficient and reliable magnetization solution for industrial applications, balancing thermal stability, magnetic coupling efficiency, and manufacturing practicality.
